Hello sir. Thank you for your reply. Actually my father is a printing machine mechanic. I am in UAE. Now he is working for komori sprint. He is not using camera phone and I have no photos. He is telling when taking screen from side to side there are lines. Not from tail to head.

 

Am not sir am very younger just trying to start a career for printing press and printing machine mechanic

 

Hi sir:

Normally, when this happen is the ball bearing in the cylinder, to due the normal wear in the ball bearing.

Only the factory, has the tolerance, that they need for to replace, very Important!!

However you must test all adjustment, from Ink Roller, Water, Pressure, and paralelism of cylinder.

If there are ALL o.k proceed with the before indications above

 

Thanks alot sir. But if bearing problem there may be some vibrations or sound. But not that anyway my father will cross check one more time and if found surely i will let u know.

Thanks sir for your valuable time.
Hope you will help more

 

ok sir

Let me know, sincerely
